What characterizes English bond?
A brick bonding pattern that alternates between headers and stretchers in each course.
What is Flemish bond?
A brick bonding pattern that alternates headers and stretchers in each course.
Describe English garden wall bond.
A brick bonding pattern that consists of alternating stretchers and headers, typically used for garden walls.
What is a Zig-zag brick bond?
A brick bonding pattern that creates a zig-zag effect with the bricks.
Define Scottish bond.
A type of brick bond that features alternating courses of headers and stretchers but is less common.
What is American bond?
A brick bonding style that typically features a row of stretchers followed by a row of headers.
Describe Flemish garden wall bond.
A variation of Flemish bond used specifically for garden walls.
What is a Herringbone bond?
A brick bonding pattern that resembles fish bones, often used for decorative purposes.
What is Facing bond?
A brick bonding pattern that is designed to show the face of the bricks prominently.
